| 摘 要： | 采用以DSP(数字信号处理器)和CPLD(复杂可编程逻辑器件)为控制核心的数字化电源平台,结合转动惯量小、响应速度快、送丝稳定的交流伺服电机推拉送丝部分,研制了数字化推拉送丝CO2焊接系统.以缓冲器为桥梁,设计了将交流伺服推拉丝与带编码器速度反馈的等速送丝融为一体的双电机推拉送丝系统.根据推拉送丝CO2焊接过程的特点,设计了焊丝的运动曲线,并提出了与焊丝运动相对应的电流、电压波形控制方案.通过软件编程的方式实现了推拉送丝CO2焊接工艺.整个熔滴过程均匀一致,焊接飞溅小,焊接热输入量小.

| Abstract: | The digital Push Pull CO2 welding system is proposed.This system utilize digital power source controlled by DSP and CPLD as platform with the AC servo push-pull feeder with the low moment of inertia,fast response,and steady feed speed.The constant feeding part combine with push-pull feeding part to form the whole feeder using buffer as a linker.Consider the characteristics of the push-pull short-circuit CO2 welding technics,the feeder speed curve,welding voltage and current waveform control program was pre-designed.According to software program,the steady push-pull CO2 welding technics was achieved with low spatter,low heat input and uniform droplet. |
